In the drawings, for the sake of clearness, the casing for the apparatus has been omitted and the supporting structure for the various parts is illustrated only in a general and fragmentary manner but it'will be understood that such details may be attended to in suitable Ways in the actual manufacture of the apparatus.

The record supporting turn table is indicated by the numeral 1 and its supporting and operating shaft by the numeral 2. The

numeral 3 indicatesin general an' electric or other suitable type of motor and the numeral 4 indicates the shaft of this motor which is provided with a worm 5. The worm meshes with a worm gea 6 fixed upon a shaft 7 supported for rotation in any suitwith. the friction face 8 of the gear 6. A tension spring 16 is connected at one end to the bearing 11 and at its other end to a suitably located fixed part and holds the bearing 11 yieldably at the limit of its sliding movement in the direction of the gear 6. .This spring 16therefore serves to normally hold the periphery of the friction wheel 15 in contact with the friction face 8 of, the gear 6 so that when the motor 3 is running, the shaft 7 will be rotated and rotary motion will be transmitted through the gear 6 and friction wheel 15 to the shaft 9. A bevel pinion 17 is fixed upon the end of the shaft 9 which is mounted in the bearing and meshes with a bevel gear 18 fixedupon the shaft 2, rotary motion being in this manner transmitted from the shaft 9 to the said shaft 2 and finally to the record supporting turn table. Inasmuch as the bearing 11 is slidably mounted, and the bearing 10 is swiveled, the first mentioned hearing may be shifted, against the tension of the spring 16, so as to move the friction wheel out of peripheral contact with the friction face of the gear 6, and when this is done power will ceaseto be transmitted to theshaft 9 and the record supporting turn table will be no longer rotated. For the purpose of shiftin the bearing 11 so as to disengage the friction wheel 15 from the gear 6, an automatic means is provided which will presently be described, and associated therewith is a manually operable means comprising a rod 19 illustrated in Figure 3 as pivotally connected at one end as at 20 to the said bearing 11 and at its other end as at 21 to the lower end of a manually operable finger lever 22 pivotallysupported as at 23 preferably within a slot 24 in the top board of the cabinet or\. casing within 'whichthe apparatus is arr nged, the upper end of the lever 22 extending above the to board as shown in the said figure and ing thus positioned for convenient manipulation. In order that, when the bearing. 11 is shifted against the tension of the spring 16 to discontinue the transmission of power from the motor 3 to the turn table shaft 2, the rotation of the record supporting turn table may rare-me be positively arrested, a brake shoe is \wheel 15 is interiorly squared and slidably disposed upon the squared portion 13 of the shaft 9, and the said wheel is thus mounted in order that it may be adjusted across the face, of the gear 6 so as to vary the speed of rotation of the shaft 9 and consequently the record supporting turntable. In order that the friction Wheel may be so shifted, a

, rock arni.- 26 is pivotally mounted as at 27 and is provided at one end with ayoke 28 engaging the hub 14 of the friction wheel in the usual manner. The opposite end of the arm 26 is provided with a fork 29 in which is engaged the lower end of a manually operable finger lever 30 pivotally supported as at 31 and capable of manipulation so as to rock the arm 26 and shift the friction wheel 15 for the purpose stated.

The tone arm is indicated in general by the numeral 32 and supports the usual reproducer or sound box 33 having means for the support of the usual stylus 34, the tone arm 32 and the reproducer 33 being of that type in which the repiroducer is supported in such a manner that it may have vertical swinging movement and is adapted to as ,sume by gravity a position with its stylus 34' restmg in engagement with the record surface. The tone arm 32 is provided with the usual downwardly extending neck 35 which is rotatably and vertically slidably fitted into the neck 36 of an amplifier 37, the connection between the parts 35 and 36 per.- mitting of vertical displacement of the tone arm independent of its swinging movement, and the said tone arm being capable of being record groove.

swung to substantially the position shown in Figure 1 in which position the reproducer and the stylus will be entirely clear of and laterally displaced with relation to the which will now be described, for bodily elevating the tone arm after the stylus of the reproducer has reached the inner end of the record groove, for swinging the said arm outwardly to position clear of the record, for subsequently swinging the, arm inwardly and at the same time lowering the same until the stylus has been brought to position resting upon the smooth surface portion of the record between the record groove and the pe riphery of the record, and for,finally moving the tone arm inwardly toward the center of the record until the stylus has been brought to position engaging in the outer portion of the record groove. a

The means referred to above includes a cam 38 which is fixed for rotation upon a shaft 39 and the rotation of which is automatically controlled by a mechanism to be presently described. The high part of the periphery of the cam is indicated by the numeral 40 and is concentric to the shaft 39 upon which the cam is mounted and extends throughout slightly more than one-half the circumference of the cam and, as illustrated in Figure 3 of the drawings, from the point a to the point 6. The low point of the cam is indicated by the numeral 41 and from this point the cam surface is comparatively abruptly elevated as at 42 to the point 6; The cam is rotated in the direction indicated by the arrow in Figure 3. numeral 43 indicates in general a supporting standard for the tone arm 32 and this standard, is provided at its upper end with a collar 44 which is clamped about or otherwise secured to the neck 35 of the tone arm so as to rigidly connect the supporting standard with the arm. From its collar 44, the standard extends downwardly and, at a point adjacent the neck 36 of the amplifier 37 is provided with a lateral bend 45'which brings its lower portion 46 into vertical alignment with the axis of the neck 35 of the tone arm. The extremity of the portion 46 is provided with a preferably spherical bearing head 47 which rests in engagement with the periphery of the cam 38. lit will now be evident that when the cam 38 has been rotated to such position that the bearing head 47 will rest at the low point 41 of the cam periphery, which is the rest position of the parts, the tone 'arm 32 and its supporting standard 43 will be in lowered position, and it is while the tone arm is in this position that the record is being reproduced. @n the other hand it will be evident that when the cam 38 is rotated in the direction indicated by the arrow in Figure 3, the supporting standard 43 will be elevated thus effecting bodily displacement of the tone arm 32 in an upward direction, this movement of the tone arm taking place after the cam surface 42 rides beneath the bearmeans provided for the purpose acts automatically to'efl'ect outward swinging move ment of the tone arm to position where it will be entirely clear of the record support- The loo

'lllltl ing turn table and the record thereon and consequently so 'disposed that it will not in any way interfere with the removal-of the record from the .turn table and the disposal upon said table of another record.

In order to effect the outward swinging movement of the-tone arm referred to above, an arm 48 is fixed upon the lower portion 46 of the tone arm supporting standard 43 and extends radially therefrom and works in a guiding member indicated in general by the numeral 49 and illustrated most clearly in Figure 14 of the drawings. The guiding member 49 is in the nature of a plate which may have the irregular contour illustrated v in the said figure or'may be of some other marginal contour as found expedient, but in any event the plate will be cut out within the bounds of its margin to provide guiding edge portions indicated by the numerals 50,

54, 52, 53 and 54. The arm 48 is illustrated in Figure 14 in one positionin full lines and in various other positions in dotted lines and in its trawel it takes the course indicated b the several arrows in the said figure.

hen the tone arm is lowered to reproducing position, which may be considered as the beginning of a cycle of I operation of theapparatus as a whole, the arm 48 will assume the full line position shown in Figure 14, the uiding member 49 being ofcourse disposer? and rigidly supported in proper operative relation to the standard 43 and arm 48 as illustrated in Figure 1 of the drawings. As the tone arm moves inwardly toward the center of the record, the arm 48 will ride above the guiding edge por- 96mm, from the full line position shown 111- Figure 14, until the tone. armmeaches the limit of its inward movement whereupon the arm 48 will assume a position in contact or nearly inicontact with the guiding edge portion 51. At this time, in amanner which will presently be more fully explained, the cam 38 will begin to elevate the tone arm supporting standard 43 to bodily elevate the tone arm. As previously stated the reproducer is so connected with the tone arm that it may have vertical swinging movement and consequently the tone arm may be bodily elevated a predetermined distance without efiectingdisengagement of the stylus of the reproducer from. the record surface. After this time however the continued upward displacement of the tone arm will result in the stylus beingjlifted clear of the record. As the standard 43 is bodily elevated, the arm 48 will of course be darried with it and will move along or in proximity to the guiding edge 51 until it comes into engagement with the guiding edge 52. The edge 51 is perpendicular to edge 50 but edge 52 is obli uely dis ed and inclined upwardly frome ge 51'. ow as the high point of the cam 38 approaches the I bearing head 47, the standard 43 will be further elevated carrying with it the arm 48, and as this arm is. now in engagementwith the edge 52 and this edge is inclined in the manner stated, the arm will 'be caused to take the course of least resistance and will therefore be swung laterally at the same time it is being moved upwardly. The lateral swinging movement of this arm of course effects a rotation of the standard 43 about the axis of its lower portion 46, and in this manner corresponding swinging movement is-imparted to the tone arm and the arm is moved to a position clear of the record supporting turn table and laterally displaced beyond the periphery thereon. As the arm 48 is moved in the direction .stated it will of course ride upwardly along the edge 52 and will finally come to rest in the angle between this edge and the edge 53 and will maintain this position so long as the high part-40 of the cam' is traveling beneath the head 47 of the standard 43. As the point a of the cam passes beneaththe head 47, and the surface of the cam between this point and the low point moved from said table and transferred to the receiving table. Upon lowering movement of the arm 48, it will ride in contact with the guiding edge portion 53 and as this edge portion is inclined downwardly toward the edge portion 50, the arm 48 will take the path of least resistance and will be swung laterall in a direction the reverse of that efi'ecte by its riding in engagement with the edge 52. Therefore as the tone arm is bodily lowered, it is also sw ng inwardly toward the peripher of the record upon the'turn table. As t e lowering movement of the standard 43 is continued and the arm 48 rides from the edge 53 onto the edge 54, the stylus of the reproducer will be brought "to position resting upon the smooth portion of the record surface between the record groove and'the periphery of the recordm The edge 54 is inclined downwardly at a sli ht angle to'the'perpendicular, the inclination being of such degree and this-edge being of such length that thetone arm may move to and assume its full lowered-position and the reproducer ma have swinging movement to the required extent .to adapt the reproducer to rest, as usual, by gravity with movement of the tone arm to such extent asis necessary to move the stylus across the saidsmooth peripheral portion of the record and into engagement in the outer ortion of the record groove. By this time t e low point 41 of said cam 38 has been brought to position beneath the 'head 47 and the arm '48 will then assume the full line position as shown in Figure 14, which completes the 19 cycle of operation of this portion of the apparatus. At this point,' by a means to be presently explained the motion of the cam 38 will be arrested and the cam will remain stationary While the newly placed record is 116 being reproduced. Inasmuch as when the arm 48 leaves the edge 53. and passes onto the, edge 54 the change in direction of motion is abruptly in a downward direction it will probably be found advisable topro- .20 vide,'opposite and in spaced relation to the said edge 54, a baffle 55 which may be supported in any suitable manner and which will, by ofl'ering an abutment for the arm 48, prevent any undue swinging-movement of the said arm and the tone arm.

I the lower end of said edge so that the arm 48 may enter this recess to permit of the tone 'arm being swung outwardly a greater dis tance than is required to engage its stylus in the outer end of the groove of a record to of smaller size.

The necessity for the'provision of means for automatically setting in motion the cam 38 and arresting its motion in consonance with the beginning and completion of the period of reproduction ofthe recprd, will be evident at this point, and there will now be described the means provided for performing this function. A bevel gear 57 isfixed upon the cam shaft 39, and a bevel 60 pinion 58 meshes with this gear and is carried at the lower end of a shaft 59 which is vertically disposed and provided at its upper'end with a bevel gear 60. A shaft 61 is mounted counter to the shaft 59 and has fixed upon it a bevel pinion 62 which meshes portion of the shaft 61 is the hub 64'of a friction wheel65. This construction is clear- 1y illustrated in Figure 5' of the drawings. and it will be observed that the face of thefriction wheel 65 directly. opposes the face 65 of the. worm gear 6 which is opposite its friction face 8 and. is indicated by the numeral 66. It will now be apparent that when the friction wheel 65 is shifted upon the shaft 61 to bring its friction face into contact with the friction face 66 ofthe worm gear 6, the shaft 61.will be connected for rotation with the shaft 7 and consequently otary motionwill be imparted by way of he shaft 59 and'the interposed gearingy to the cam shaft 39 and the cam 38 thereon. Automatic means is provided for shifting the friction wheel 65 and comprises a rock arm 67 pivotally mounted as at 68 and provided adjacent its pivot with a portion 69 having engagement with the hub 64 of the wheel 65 to providefor shifting of the hub upon the shaft 61 upon rocking of the arm 67. The other end of the arm is pivotally connected as at 70 to the upper end of a vertically disposed rock arm 71 pivotally supported for rocking movement as at 72 and provided at its lower end with a fork 73. The member 74 indicates in general a rocker which is pivotally mounted as at 75 and comprises a substantially horizontally disposed member 76 and an arm 77 which upstands from the member 76 above the pivot 75 this arm being formed at its upper end as at 78 for engagement in the fork 73 at the lower end of the arm 71. A spring 79 is connected at one end to one end of the member 76 of the rocker 74 and at its other end to a suitably located fixed part and exerts a downward pull upon this end of the said member of therocker. The rocker is disposed in a plane parallel totheplane posite the end to which the spring 7 9 is connected, located relatively close to, the periphery of the said cam.-- A trip finger 80 is pivotally mounted near one end as at 81 upon the member 76 of the rocker 74, the pivot 81 being located near the last men- .tioned'end of-the said member, and this trip finger 80 extends beside the said member 76 and restsby gravity in engagement with a stop pin 82 which projects from the side of the said member 76. A detent 83 is pivotally mounted as at 84 upon the said side of the member 7 6' and is provided with a nose 85 for latching engagement with the free end of the trip finger 80. Below its pivot the detent 83 is extended downwardly as at 86 and has connected to it a wire or similar connecting element 87, this wire being likewise connected by a ring or other suitable means 88 to another wire 89 which is secured. at its lower end as at 90 to any conveniently located fixed part. At its upper end the wire 89 is connected to one end of a tri arm 91 pivotally mounted between its en sas at 92 and having its other or free .endlocated in the path of inward swinging movement of the arm 48. :The shorter end of the trip finger 80 projects as at 93- be-- occupied bythe cam 38 and with its end op- I of a pin 94 which 'is' carried by the cam 38 and projects from one face thereof.

As heretofore stated, in the rest position of the cam 38, the bearing head 47 is in position bearing upon the periphery of the cam at the low point 41, this being the position of the parts duringthe period of reproduction. As the cam approaches and reaches this osition in its previous cycle of movement, t e in 94 will be brought into engagement wit the projecting end 93 of the trip finger -80, and. as the opposite end of the trip finger is engaged by the detent 83, the rocker 74 will be rocked against the tension of the ring 79 and this movement of the rocker will, throu h the intermediate connections 77, 71 and 6 effect shifting of the friction wheel 65 out of engagement with the worm: gear 6 so that transmission of motion to the cam 38 through the shaft 39 will be discontinued. Upon cessation of movement of the cam 38, the cam will be in position with the bearing head 47 resting in engagement with the low point 41 of its periphery and the parts will maintain this relation during the period of reproduction. However, as the tone arm approaches the limit of its inward swinging movement, the arm 48, which moves in consonance therewith,

. will ride upon the free end of the trip arm 91 thereby exerting a pull upon the wire 89 tending to straighten this wire (the pull upon the wire exerted by the wire 87 normally distorting it from a straight line as illustrated in Figures 3 and 4) and the pull will therefore be exerted by the wire 87 to disengage the detent 83 from the free end of the trip finger thereby releasing the rocker 74 and permitting the said rocker to be returned to 1 its normal position through the medium of the spring 79. As the rocker moves to this position, its arm7 7 will be swung in such manner as to rock the arm 71 and the arm 67 and shift the friction wheel 65 into clutch with the worm gear 6 thereby establishing drive connection between the shaft 7 and the cam shaft 39 and setting in motion the. cam 38. Release of the trip finger 80 of course permits the pin 94 upon the cam 38 to pass the end 93of the said trip finger.

There will now be described the meansv provided for supporting therecords to be reproduced, for transferring said recordsfrom the supporting means to the record supporting turn table, and for transferring the records from the. said turn table to the record receiving means. This portion of the apparatus, so far as it relates to the record storage means, comprises a record supportlng table indicated in general by the numeral 95. This table preferably comnumeral 110 to prises a plate 96 which may be of any -The legs 98. are shorter than the legs 99,

and the forks 100 of the two sets of legs rest slidably in engagement with the side rails 101 of a supporting framestructure ,indicated in general by the numeral 102, the said rails 101 being supported by standards 103'and 104. By reference to Figures land 2 of the drawings it will be observed that the record storage table 95 and its supporting frame structure 102 are located at one side of the record supporting turn table 1. It will also be observed, particularly by reference to Figure 2, that the supporting standards 103 of the frame structure 102- are shorter than the'standards 104 so that the rails 101 are inclined downwardly in the direction of the plane of the said turn table 1. Likewise the table 95 is so arranged upon the supporting frame structure that its shorter legs 98 will be located next adjacent the record supporting turn table. The lower end portions of the rails 101 are deflected at an obtuse angle to their upper portions in an upward direction as indicated by the numeral 105 and these deflected portions constitute retaining fingers for engagement by the peripheries of the records disposed upon the table 95.

The means provided for removing the records from the pile upon'the table 95 and depositing them upon the recordsupplortihg turn table 1 includes a shaft 106 w ich, by means tobe presently described, is to be rotated in consonance with the other mechanisms of the apparatus. This shaft supports and actuatesv a record gripping means which functions between the record storage table 95 and the record supporting turntable 1. The record gripping means 106 and which has a gradually increasing radius from its low point, indicated by the its high point indicated by the numeral 111' where it is curved out-v wardly along a reverse arc to form a nose .-ate form and corresponding in its general contour to that ofthe jaw 113. The jaw 1-14 is supported at the free end ofan arm 115 which is pivoted at its other end as at 116 to one side of the disk 108 at sucha point that the arm 115 may be swung upon the pivot to bring thejaw 114 into coactive relation to the jaw 113 as shown in Figure 6 or may be swung inthe reverse direction to cause the aw 114 to recede from or move out of active relation tothe jaw 113. The

swinging movement of the arm 115 in the latter direction is limited by a step pin 117 upon-the side of the disk 108, and the pivoted end of the said arm is preferably beveled as at 118 to adapt it for coaction with a gravity detent which is indicated by the numeral 119 and wh ch is pivotally mounted as at 120 uponthe said side of the disk 108. The pivot 120 forithe gravity detent 119 is located nearer one end than the other of the said detent so that the detent has a 1 normal tendency to.overbalance in one direction, its heavier end being indicated by the numeral 121. The opposite end of the detent is provided with a shoulder 122 and this end of the detent is likewise preferably beveled as at 123, in advance of the shoulder. Stop pins 124 and 125 upon the face of the disk 108 at opposite sides of the portion 121 of the de tent 119 serve to limit the movement of the detent upon its pivot in either d rection. Preferably a counterweight element 126 is provided upon the end 118 of the arm 115.

In disposing the records it upon the record storage table 95, the desired number ofrecords are placed upon the table in shingled relation, and the table will be adjusted longitudinally of the rails 101 of the supporting frame structure 102 to such initial pos tion that the uppermost record of the stack will project beyond the deflected .portions 1.05 of the said rails and will rest at its periphery in engagement with the. cccentric peripheral portion 109 of ,the disk 108 as shown in'Figure 7 of the drawings,

one or more of the records immediately beneaththe uppermost record of the stack rest- "ng at their peripheries against the deflected portions or retaining fingers 105 ofthe rails 101. When thememher 107 is at rest it will occupy approximately the position shown 'in" Figure 7 except that it Will through a slight rotation of the shaft 106 in a counter-clockwised rection, be rotated a short distance backwardly' from this position and in the direction the reverse of that indicated by the arrow in the said Figure 7- In the period in the cycle of operation of the apparatus where the records are to be transferred, the shaft 106 will be rotated in a counter-clockwse direction correspondingly rotating the member 107, and the eccentric peripheral portion 109 of the memher will ride against the periphery of the uppermost record and because of the eccentric curvature of the same, will act against the record to slightly move or shuck the pile of records upon the record storage table thus influencing the legs 98 and 99 of the record storage table to move downwardlya short distance along the ra'ls 101 of the supportihg frame structure 102. The rotation of the member 107 in the direction stated is continued until the nose 112 of the member rides past the periphery of the said uppermost record and the engaging face of the jaw 113 is brought into the plane of the under side of this record whereupon the record will slp or slide downwardly and rest at its peripheral portion upon the engaging face of this jaw. In the meantime the detent 119 has assumed by gravity a position with its portion 121 resting in engagement with the stop pin 125, and the jaw 114 and its supportng arm 115 will at this time drop by gravity to such position that the jaw 114 will overlap the peripheral portion of the jaw 113. In this movem'entjof the jaw 114 and its arm 115,

the beveled end 118 of the arm will ride over the beveled end 123 of the detent 119 and engage behind the shoulder 122, and in this. manner the jaW-114 is locked in gripping engagement with the peripheral portion of the record. The shaft 106 is then rotated in a clockwise direction as indicated by the arrow in Figure 6 of the drawngs and therefore in the general direction of the record supporting turn table 1 carrying with it the record which has been gripped and depositing the same upon the said turn table. When the shaft 106 has been rotated to the limit of its movement n this direction the member 107 will assume the posi tion shown in Figure 7 of the drawings,

having been moved thereto from the position shown in Figure 6. During the period of transfer 'of the record the leverage ex- I erted by the. we ght of thesame against the jaw 114 has served to bind the end 118 of the arm. 115 against the shoulder of the detent 119 with suiiicient force to maintain and the detent 119 will then swing by gravity into position resting againstthe stop pin-i124 and out of. restraining engagement with the arm 115 thus permitting thisarm' .and the jaw 114 to'swing downwardly by "ifg ravity. out of grpping; engagement with 'the' record. Through the 'operating".means 'fortheshaft 106 which, asbefore stated, 'will' vpresentlybe described, the shaft and consequently the member 107 is now given a slight rotation in a counter-clockwise diturn table opposite the side-at 'which the' record storage table .95 is located. This.

means comprises a shaft 128 which is rotated in consonance with and by the same: mechanism which operates to rotate the shaft 106, and mounted upon the said shaft -128 is a record grippingmeans comprising a relatively fixed jaw which is indicated in. general by the numeral'129 and a movable aw for coaction therewith indicated in general by the numeral 130. These 'aws are of arcua-te form and have substantially the .same degree of curvature as the periphery of the'r'ecord to be handled and they are designed to coact-in substantially the same manner as thejaws 113'and 114 previously described. The numeral 131 indicates arms which are fixed in spaced relation upon the s'haft'128' and which are provyided' upon their opposing sides each with a pair of spaced supporting and guiding. pins 132 arranged parallel to'one edge ofthe respective arm 131. Thesfixedjaw 129 is rovidedat its ends with'cams 133 pref- 4 era ly integral therewith and provided ,With

rearwardly extendin shanks 134: each formed with, a "slot 135'- receiving the pins 132. on the respective arm 131, In'this man ner the fixed jaw 129 is supported-between the arms. 131' for bodily swinging movement with said arms, andthe pins 132 furthermore support this jawfor sliding movement upon the arms so that it may bemov'ed inwardly toward the shaft 128 or outwardly from said shaft. Springs 136 are connected to the ends, of-the shanks 134 and to the arms 131 near the outer' ends of the said arms and yieldabl yhold the jaw 129 shifted in an outward direction, inward shifting moveihent of the jaw being against the tensionof these springs. Each of the cams 133,is provided with a cam edge indicated by the numeral 1 375 a'ndthese cam edges ar 80061115119 the axis of the shaft 128. The cams 133 prorecti'on, bringing the jaw- 113 clear of therecord.

-ject from the plane of the jaw 1 29 and their cam edges-137 are curved from' points coincident. with the outer edge of the sa'idfjaw' and infect merge withsaid edge, the high points of the cam edgesbeing indicatedby the numeral138 and the lowpoints by the numeral-139. A 1

An'arm 140 is fixed'upon the shaft 128 between the arms 131 and supports a cam 141 the working edge of which is indicated bythe numeral 142-and has its high point [indicated by the numeral 143 and its low point'by the numeral 144. .The'movable jaw tion by an arm 145 pivotally mounted as '130 is supported at its intermediate por- I at 146 upon one side of the arm 14011831 the outer end of-the-iatter, and the arm 145' is adapted to be swung upon its pivot to bring, the jaw' 130 intocoactive relation to the jaw 129 or to move the jaw 130 out of such relation, the movement of the arm in this latter direction being limited by a stop pin 147 upon the side of the arm 140. The arm 145 is preferably provided, with a counterweight 148. at one side of its pivot 146 and this pivot is located nearer ne end of the arm than the other, the shorter.

end of. the arm being beveled as' at 149. A detent 150 is pivotally mounted near one end as at 1551 upon theside of'the arm 140 andfat its said end is beveled as at 152 and formed with a shoulder 153. The opposite end portion of the detent is longer than the shoulder and. is. indicated by the numeral 154 and has sufficient weight to over-balance the detent. The pivotal movement of the detent is limited by stop upon the side of the arm 140.

When in a position of rest the parts comprising the gripping device above described will assume approximately the positions shown in Figure '9 except thatthe shaft 128 and the parts supported'thereby will be rotated in acounter-clockwis'e direction a short distance." At the proper period in the cycle of operation of the apparatus, the grip:

pins 155'and 156 ping device described operates automatically to grip the record which is support? ed upon the record supportin turn table and which has been reproduce and to remove this record from the said table and deposit the 'same'upon the receiving table 127.

The first operation involves rotation of the shaft'1 28 in a counter-clockwise. direction through an arc of substantially 180 and as the shaft rotates in this manner thecam edges 137- of the cams 133 will ride against the-periphery ofthe record upon the turn table and these came and the relative fixed jaw .129 which is supported between them, will be shifted inwardly toward. the shaft 128 against the tension of thesprings: 136 until a the edge of the jaw 129 passes the edge of the record whereupon the said jaw will be proectefd by the springs 136.110 position lying evant/e Q beneath the periphery ofthe record. As the shaft is rotated in the manner stated the det ent 150 will assume a position resting by gravity against the pin. 156 substantially as illustrated in'l igure 8 and by the time the shaft reaches the position shown in said figure, the jaw 130 and the arm 145, the beveled end 149 of said arm will 'but when the record is deposited upon the.

ride past the beveled end 152 of the detent 150 and seat behind the-shoulder 153., In this manner the jaw 130 is locked in grip ping engagement with the-periphery of the record. lihe shaft 128 is then rotated in a clockwise direction and the record grippr between the jaws 129 and 130 will be carrieo over-and deposited upon the. surface of the table 127 or upon the uppermost record upon. this table it other records have previousi been deposited thereon.- Up to this time thi engagement between the end 149 of the arm "145 and the shoulder 153 of the detent 150 has been maintained throughthe leverage exerted by the record against the jaw 130 receiving table 127 the -jaw 130 and arm 145 are relieved of this stress and the detent 150 then immediately swings by gravity to posit on resting against thestop pin 155 and disr gages from the end of the arm 1415 thus permitting this arm and the jaw supported thereby to swing downwardly out of gripping engagement with the record as -illus tra ed in Fi re 9' of the drawings v The receiving table 127 is designed to bedepressed 'a distance equal. to the thickness of arecord as each succeeding record is deposited thereon and this movement of the 9 table, which will presently be more specifi- .cally described, is effected through the pressure exerted. against the upper side of the record by the jaw 129, this jaw being located a'suficientdistancein advance of the.

iew 130, whenthe jaws are in coactive relation; to adapt it-to exert jsuch pressure at a point above the eripheral portion of the table-127 before t ejaw130 has cleared the periphery out the said table.

i It is intended that the records shall be do i posited upon the table- 127 in stacked rela -'tion-,- and the said table is preferably equal in diameter to the diameter of the "records, and in; order that the records may be maintained in a uniform stacked are -"arranged in' vertical relation, abutment and guidi position beside the peripheryjof the table at spaced points in said periphery and serve as abutments'. for

the p'e'rip eries of'the records when deposited upon the table menu ofi'ts deposition upon the table 127,

the record will project atits periphery apins 157 However at the moshort distance beyond the periphery or the tableand it is therefore necessary to shift the record upon the table .to bring its periphery into engagement with the stop pins 157 and therebycause it to assume its proper stackedposition and'this is edected through 4 The record receiving table 127 is support ed upon the upper end of a standard 158 supported for vertical sliding movement in any suitable manner as for example by guide bearings 159 and 160. The lower portion of the standard 158 which works in the bearing-160 is reduced in diameter as indicated by the numeral 161, and a spring l62 is fitted onto this portion of the standard and bears at its lower end upon the bearing 160 and at its upperendagainst a collar or. shoulder 163 upon the said standard. -This spring 162 serves to yieldably'support, the table 127 in an elevated position but as previously statedtlie table isto be depressed a distance equal to the thickness of a record. as each' succeeding record is deposited thereon, and

in order that the table may be restrained against upward or return'movernent after each depression, thereof, means is provided which will now be described. T he numeral 16 1 indicates a rocker which is pivotall "supported'as-indicatedby the numeral 16 atone side of the standard 158 and is provided at one'end with a yoke 166 embracing said standard and seating beneath a collar 167 thereon. ,The other end of the rocker .1614is provided "with a similar yoke 168 which engages'beneath a collar 169 upon a Y locking bar 170 whichba'r is mounted inany suitablemanner for vertical sliding movement. fl'lhe bar 170 isprovided along one side with a series or rack teeth'171, and a 'pawl172 is pivotally mounted as'at 173 b8,

. side the bar 17 0 and has a tooth 1741 for coaction with the rack teeth 171-. It will now I be. evident that when the table-127 is displaced-against the tension of the spring 162,

movement. will be imparted to the rocker 164:1;0 shift the bar 17 O upwardly a distance of one tooth whereupon the tooth 174 of the .pawl- 172 will, by its engagement'with the.

teeth 171, hold the'bar in this position and thus restrain-the standard 158 from'upward or return -movement under the action of the spring 162. The pawl 172' is preferably providedwith a finger piece 175 whereby it may be manually disengaged from the rack teeth 171 so as to permit of upward movement'of the standard 158 and the receiving table 127 supported thereby. This will of course be done when a pile of records which have been. deposited upon the receiving table are removed or when a greateror less number of the pile or stack are removed and 1n .order to in either event limit the upward Movement of the table 127 to the extent that its upper surface, or the upper surface 'of the uppermost record remaining thereon Will be brought to the proper level to receive subsequently deposited records, a gage de- Evice such as illustrated in Figures 1 and 2 of the drawings is'employed. This device is indicated in general by the numeral 176 and comprises-an arm 177 extending radiallyfrom the upper end of a spindle 17 8 whereby it is adapted to be swung in a horizontal plane. The spindle 178 is mounted beyond the periphery of the table 127, and the arm vis adapted to be swung to position overlying the table as shown in dotted lines in Figure 1 or to position clear of the table as shown in full lines in said figure. The arm is provided at its free end with a head 179 having a flat under-surface 180 adapted to be engaged by the upper surface of the table 127 or the upper side of the uppermost record upon said table, when the table is permitted ;to rise through the influence of the spring 162. Thus all of the records may be removed from the record receiving table at any time or any desired number of records may be removed and after such removal the arm 177 will be swung to position overlying the table and the pawl 172 will then be disengaged to permit the spring 162 to elevate the table until its upper surface or the upper side of the uppermost record thereon is brought into engagement against the flat face 180 of the head 179 at which time the table will be in proper position for the depupon the shafts 106 and 128 and mesh respectively with a series of rack teeth 183 and 184 formed upon a shiftablerack bar 185. The pinion 181 is of slightly larger diameter than the pinion 182, the pinions being thus proportioned for the reason that while the shaft 128 is to be rotated through an arc of substantially 180 in order to effect transfer of the record from the record supporting turn table to the record receivin table which tables are located in the same orizontal plane, the shaft 106,1'e-n,

quires to be rotated a, less angular distance inasmuch as the record storage table is .ina clined with relation to the plane occupliaed e- ,v r185 isefiected through the cam 38 and anintermediate connection comprising a rock lever 186 piv-' otally supported for rocking movement as. at 187 and provided below its pivot with an the record supporting turn table. ciprocation of the rack a arm 188 having a longitudinal slot 189 in--.

which works a pin 190 upon the face of the said cam 38. The pin 190, working in the slot 189, acts as a crank to' impartrocking motion to the lever 186 and the. upper en of this lever engages a fork 191 provided at the end of one arm 192 of an angle lever 193 which is supported for rocking moves ceiving a connecting pin 197, this pin being provided at its upper end with a preferably milled head 198 whereby it may be adjusted in the opening 196. The wall of the opening is formed with a longitudinally extending groove 199, and the pin 197 is provided with a laterally projecting stud 200 which is adapted to seat in said groove 199 when the pin is rotated to a predetermined position and lowered in the opening 196. The pin in this position projects at its lower end into a slot" 201 formed transversely in a broadened portion of the rack bar 185. It will now be evident that as the cam 38 makes a complete revolution, the lever 186 will be rocked to the limit of its movement in one direction and then in a reverse direction. The angular movement thus imparted to the angle lever 193 will result in a reciprocation of the rack bar 185 first in one direction and then in the opposite direction. Therefore the shafts 106 and 128 will be rotated first in acounter-clock wise direction to adapt the record gripping means which are associated therewith, to respectively grip records located upon the record storage table and record supporting turn table, the said shafts being then rotated in a clockwise direction to transfer the said records and deposit them respectively upon the record supgortin turn table and receiving table. houl it be desired to temporarily discontinue the automatic operation of the apparatus as, for example, when it is desired to repeatedly reproduce. any particular record, this may be accomplished by elevating the pin 197 in the opening 196 until the stud 200 is located above the plane of the upper side of the arm 195 whereupon.

the pin may be rotated to bring the stud out of registration with the upper end of the groove 199 and to position resting upon as ment as at 194. The other arm of this lever indicated by the numeral 195, is formed with an opening 196 rotatably and slidably re-- Li s ' the slot 201.

. During the period of operationof the apparatus' to effect transfer of the records,-it 1s I of course essential that the record supporting turntable be stationary and it is essential that at the termination .ofthisl ps riod motion shall again be imparted to'the] said turn table to efiect reproduction of the equally record which has been placed thereon. lln

. order that this may be accomplished means rod 19.which is connected .20

is provided for automatically actuating the to the bearing 11 move the friction engagement with worm gear and engagement with means comprlses a forthe shaft 9 so as to wheel into and out, of the friction face 8 of the likewise into and out of the brake shoe 25. This control cam which is indicated-in general by the numeral 202 and which is lined upon the shaft 128 for rotation therewith. This cam isbest illustrated in Figures 12 and 13 of the drawings and is provided with a groove 203 formed in one face thereof and extendin on an arc concentric to the axis of rotation of the cam. This groove 203 comprises a portion 204 which is of uniform I depth from one end 205 of the groove to H substantially the point indicated at 200.

' From this point to the point indicated hy the numeral 207, the bottom wall of thegroove is inclined as at 208 to gradually increase the depth oi the groove, the groove terminating in a portion 209 of greater depth than any other portion of the groove.

The oove is provided adjacent the point 1 206w1th'an eccentric branch 210 of the same depth as the portion 204: of the groove. A gate 211 is pivotally mounted as at 212 between the groove and its branch 210 substantially at the point 208 and adapted to assume by gravity substantially the position shown in Figure 12 when the cam is in the position shown. The gate 211 extends between the groove 203 and its hranch 210'and from its pivot 212 in a direction away from the portion 208 of the groove. A second gate 213 is mounted for swinging movement within the branch 210 at a point near the end thereof and opposite the point 207 and is yield-- ably held by means of air-spring 214, associated with its in- Figure it being adapted- -to have pivotal movement againstthe tension of the spring 214 in the direction indicated by the arrow in Figure 12"1inder conditions which will presently be described. The cam 202 is designed to act upon a. rock arm 215. which is .pivotally pivot, in substantially the'po- '12 of the drawings,

are s51.

mounted between its ends as at 216 and has one end pivotally connected as at 21'? with the rod 19. Near its other end the rock arm 215 is formed in sections and the outer sec tion, indicated b the numeral 218, is pivot-.

ally connected with the main or inner section seat 219 in such manner that the section 218 may have swinging movement about an axis at right angles to the axis of the pivot 216. The free end of the section 218 ot the rock arm 215 is deflected laterally as at 219 and provided with a rounded terminal 220 which I wheel 15 in driving contact with the face of the gear 0. However upon initial rotation of the shaft 128,.the cam 202 will be rotated in a counter-clockwise direction causing the portion 208 oif'the bottom wall of the groove to ride againstthe said end of the rock arm 215 rocking this arm and actingupon the rod 19 to shift the shaft 9 and move the friction wheel 15 out of driving engagement with the face of the gear 6, the periphery of the said friction wheel being at the same time brought into contact with the brake shoe 25. As the cam 202 continues to rotate. the bottom wall of its portion 204- will ride-against the end of the arm 215 until the end 205 of the groove substantially reaches the said end of the arm whereupon the cam will be rotated in the reverse or a clockwise direction until the free end of the gate has beenbroughtopposite the said end 220ml the rock arm 215. This gate will now defleet the end of the arm, and because of the 'joint 219 therein, the section 218 of the arm may swing upwardly the required distance to permit the extremity of the arm to travel in the branch 210 of the cam groove. Tn the continued rotation of the cam. thegate 213 will ride beneath the end of the section 218 of the arm and the gate will he deflected against the tension ofthe spring 214, and

after the said end of the said section of the arm has past the said gate it will drop into the deep port-ion 209 of the cam groove thus permitting the spring 16 toast immed ately ,to shift; the shaft 9 to bring the friction wheel 15 into driving contact with thehface the shingled relation heretofore described and shown .in Figures 6 and 7 of the drawings, and the apparatus is set in operation by starting the motor. As the stylus of the reproducer approaches the center of the record or in other words nears the end of the period of reproduction, the arm 48 will ride against the trip arm 91 tripping the detent 83, releasing the arm 80, and rmittin the spring 79 to actuate the rocker 74 an by the intermediate connections 71 and 67, efi'ect movement of the friction wheel 65 into driving engagement with the worm gear 6 thus setting in motion the cam 38. As the cam rotates and its portion 42 rides beneath the lower end of the supporting standard 43, this standard will be gradually elevated and the tone arm will be bodily moved in a corresponding direction. However the reproducer is connected .with

' the tone arm, as previously stated, in such manner as to permit of swinging movement with relation to the said arm, and therefore the stylus willbe maintained in reproducing engagement with the record groove until the inner end of the groove passes the stylus and the reproduction of the record is thus completed. By this time the high part of the cam 38 will ride beneath the lower end of the standard 43 thus further elevating the standard and the tone arm and finally bringing the stylus of the reproducer clear of the record. In this movement of the standard the arm 48"will be moved upwardly alon the guiding edge portion 51 of the mem er 49, and striking the edge portion 52, wilhbe influenced by the inclination of this edge portion to swing laterally thus effecting bodily swinging movement of the tone arm outwardly to position clear of the record. In the meantime, and in the rotation of the cam 38 the rack bar 185 will be shifted so as to effect operation of the record gripping devices associated with the shafts 106 and 128 in the manner previously described. Thus the record which has been reproduced will be lifted from the record supporting turn table, which in the 'manner previously explained has been brought to rest, and will be deposited upon the receiving table, and a new record will be lifted from the stack upon the storage table and deposited upon the. turn table.

After deposition of the record upon the record supporting turn table, the tone arm willbe swun inwardly and gradually lowered due to the travel of the arm 48- down the guiding edge portion 53 of the member 49, and the stylus of the reproduoer will be brought into contact with the smooth portion of the record between the record groove and the periphery of the record, and, as the arm 48 passes down the edge portion 54, the lowering movement of the tone arm will be completed and likewise the arm will be further swung inwardly a sufiicient distance to move the stylus across the said smooth portion of the record'and into the outer end of the record groove. At this time the record transferring devices have been restored to normal position and the engaging end of the rock arm 215 has dropped into the deep portion 209 of the groove in the cam 202 and the shaft 9 has been shifted so as to bring the friction wheel 15 into driving engagement with the gear 6 whereupon the turn table will be set in motion and the operation above described will be repeated.
